A base trait for scenes that can be run from within the gameloop

Required methods

fn think(&mut self, game: &mut GameControl)

Runs the think logic. Ideally, processes all the ThinkerSystems in this scene.

fn draw(
    &mut self,
    drawing: &mut Box<dyn DrawControl>,
    transform: &DrawTransform,
    interpolation: f32
)

Runs the draw logic. Ideally, processes all the DrawerSystems in this scene.

fn start(&mut self, game: &mut GameControl) -> bool

Called to run initialization logic. Ideally, calls ThinkerSystem::start() on all the ThinkerSystems in this scene.

fn end(&mut self, game: &mut GameControl) -> bool

Called to run deinitialization logic. Ideally, calls ThinkerSystem::end() on all the ThinkerSystems in this scene.

fn entity_count(&self) -> usize

Returns the number of Entities in the scene

fn component_count(&self) -> usize

Returns the number of Components in the scene

Implementors

impl<T: SceneType + 'static> BaseScene for Scene<T>[src]

fn think(&mut self, game: &mut GameControl)[src]

Processes all the ThinkerSystems in this scene. You normally do not need to call this yourself, as the Gameloop handles this for you.

fn start(&mut self, game: &mut GameControl) -> bool[src]

Allows all the ThinkerSystems to process their "start of scene" actions. You normally do not need to call this yourself, as the Gameloop handles this for you.

fn end(&mut self, game: &mut GameControl) -> bool[src]

Allows all the ThinkerSystems to process their "end of scene" actions. You normally do not need to call this yourself, as the Gameloop handles this for you.

fn draw(
    &mut self,
    drawing: &mut Box<dyn DrawControl>,
    transform: &DrawTransform,
    interpolation: f32
)[src]

Processes all the DrawerSystems in this scene. You normally do not need to call this yourself, as the Gameloop handles this for you.

fn entity_count(&self) -> usize[src]

Returns the number of Entities in the scene

fn component_count(&self) -> usize[src]

Returns the number of Components in the scene
